SASH FAsTEnE Application filed September 3, 1926. Serial No. 133,345.

The present invention relates to certain new and useful improvements in sash fasteners, and has for its object to provide a device of this character which embodies novel featuros of construction, whereby both sashes are latched against sliding movement and the i'neeting rails of the two sashes are simultaneously drawn together to provide a tight joint and prevent rattling.

Among the further objects of the invention are to provide a sash fastener which can be easily applied to the meeting rails of any conventional sliding sash window without mutilating or disfiguring the same, which I can be easily manipulated either to latch or release the sashes, and which will latch the meeting rails of the sashes firmly together in such a manner as to provide a weather-proof joint and at the same time prevent any unauthorized opening of the window from the outside. of the building? I lVhile one particular embodiment of the invention is shownand described in detail in this application for illustrative purposes,

modifications and changes can be made in the details of construction without departlng from the spirit of the invention.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a transverse vertical sectional View through the meeting rails of a pair of sashes, showing the sash fastener as applied thereto.

Figure 2 is an enlarged top plan view of the sash fastening device when detached from the window sash, the position of the locking bolt when in operative position being shown by full lines and when in inoperative position being shown by dotted lines.

Figure 3 is a front elevation of a portion of the sash rail with the locking device applied thereto.

Corresponding and like parts are referred to in the following description and indicated on all of the views of the drawing by like characters.

Referring to Figure 1 of the drawing, the

numeral 1 designates the meeting rail of an.

tirely through the meeting rail 2 of the lower sash, and a guide sleeve 3 is fitted in this opening, said sleeve extending entirely through the opening from end to end, and being provided at its outer end with :a circular plate 4 which fits against the front of the sash rail and may besecured thereto in any suitable manner. The inner face of the meeting rail 10f the upper sash is provided with a socket, and a thimble shaped keeper 5 is fitted within the socket, said keeper being so positioned as to be in alignment with the guide sleeve?) when the two sashes are closed. The keeper 5 is securely fastened to the sash in some suitable manner, being shown in the present instance as provided at its inner end with a suitable opening for engagement with the head of a screw 6. The screw can be readily inserted in position through the open end of the keeper and serves to securely an chor the keeper to the sash. A locking bolt? is slidably mounted within the guide sleeve 3, being adapted to have the nose thereof projected into the keeper 5 to hold the two sashes against relative sliding movement. A stem 8 projects from the outer end of the latch bolt and extends through an opening in the plate 4, a finger piece'9 being threaded upon .or otherwise secured to the projecting end of the stem.-.- Surrounding'the stem is a coil spring 10 which is interposed between the end of the laterally project-ing lugs 11 and 12 which are arranged longitudinally thereof. The keeper 5is formed witha longitudinal slot 13 Y which opens through the end of the keeper and communicates at its inner end with a lateral slot 14. In a similar manner the end of t-heguide sleeve 3 is provided-with a longitudinal slot 15 which is inregistry with the longitudinal slot of the keeper and communia cates at its inner end with a lateral slot 16. The opposite end of the longitudinal slot 15 opens through the end of the guide and communicates with a notch or cut-away portion 17 The notch 17 and two lateral slots 16 and 14 are all arranged on the same side of the two aligning longitudinal slots 13 and 15, and the distance between the notch 17 and either of the. lateral slots 14 or 16 is exact-1y equal to the distance between the two lateral lugs 11 and 12 of the latch bolt. When the latch bolt is rotated to bring the lateral lugs into the longitudinal slots it can be moved longitudinally and thereby moved into either operative or inoperative position. The locking bolt can then be pulled rear wardly to the limit of its movement and rotated to turn the lug 11 into the longitudinal slot 15 of the guide sleeve, and the leg 12 into the notch 17. This position is shown byidotted lines on Figure 2, and the latch bolt is then securely held in inoperative position so that the sashes can be moved freely up and down in the usual manner.

hen it is desired to latch the two sashes the latch bolt rotated to bring the lugs 11 and 12 into the longitudinal slots, after which it is released and permitted to be moved inwardlly into operative position by the action of the spring 10. The lug 12 then engages the inner end of the longitudinal slot 13 of the keeperand the latch bolt can then be rotated to move the lug 12 into the said lateral slot, the lug 11 being simultaneously moved into the notch 17. One side of the lateral slot 14 of the keeper is inclined, as indicated at 14, thereby p1 riding a cam portion to engage the lug 12 as it is turned into position and forcibly slide the latch bolt inwardly to the limit of its movement. The finger piece 9 engages the plate 4 when the bolt is mover inwardly, so that the cam action of this elined edge let of: the slot serves to forcibly draw the meeting rails otthe sashes together, thereby providing a tight joint and prevent rattling. The corresponding side of the notch 17 is securely inclined at 17*.

As shownmore clearly by Figures 2 and 3, the fingerpiece 9 is laterally elongated ,so that it can be more readily grasped by the "'iingers to be rotated in either direction. The outer face of the finger piece is shown as provided with arrows 18"which are associated with the words Open and Look to indicate the proper direction for turning the fingerpiece to rotate the bolt in the necessary direction for latching or releasing the same. notch and lateral slots cooperate effectively with the lugs of the bolt to hold the bolt in either an operative or an inoperative posi tion, and when the bolt is moved into operative position the cam edge portion 14 of the lateral slot 14 cooperates with. the lug 12 to draw the meeting rails of the twosashes se curely together.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: V

1. In a sash fastener, the combination with a tubular keeper adapted to be embedded in one of the sash rails, a fastening member engaging the inner end of the keeper and anchoring the keeper in the sash rail, a guide sleeve adapted to extend transversely through the other sash rail, a plate at the outer end of the guide sleeve for engaging the face of the sash rail, alatch bolt slidable and rotatable in the guide sleeve, a stem projecting from the latch bolt through the plate, aspring surrounding the stemand interposed between the'latch bolt and the plate, a linger piece applied to the projecting end of the stem and engaging the plate to limit the inward movement of the latch bolt, a lug on the latch bolt, a bayonet slot in the keeper adapted to receive and interlock with the lug to hold the bolt in operative position, said slot having a cam portion arranged for cooperation with the lug to forcibly draw the two sash rails together when the lug is rotated into the transverse portion of the bayonet slot.

2; In a sash fastener, the combination with a tubular keeper adapted to be embedded in one sash rail, a guide sleeve adapted toextend transversely through the other ,sash rail, a plate at the other end of the guide sleeve adapted to engage the face 01? the sash rail, a latch bolt slidable and rotatable in the guide sleeve and adapted to be projected intoengagement with the keeper, a stem projecting from the end of the bolt and extending through the, plate, a spring surrounding the stem and interposed between the bolt and the plate, a finger piece applied to the projecting end of the stem and adapted to engage the plate to limit the inward movement of the bolt, and a pair of spaced lugs projecting from the bolt, the keeper and guide sleeve being formed with corresponding longitudinal slots which receive the lugs when the bolt is moved in and out, the keeper also having a transverse slot and the guide sleeve being formed with a transverse slot and notch, the

two transverse slots being equidistant from,

the notch and the notch and one of the transverse slots being adapted to receive the two lugs to hold the bolt in either an operative position or an inoperative position.

In testimony whereof I afiix my signature.
